From 03bf301d825ff0e360be67b4839bdb11f2f61774 Mon Sep 17 00:00:00 2001 From: Daisuke Nojiri Date: Fri, 7 Oct 2016 13:59:36 -0700 Subject: vboot: Stop creating backup space in TPM There is no code which uses the backup space in TPM created for vboot nvram. All chromebooks currently supported at the trunk store vboot nvram in flash directly or as a backup.
